Q: Safari keeps crashing after 1st bookmarks sync with Chrome

I ran into the same issue, and I have a partial solution for you.

I had to restore my phone as new, then during the set-up, select "set up as new" (not restore from a back-up). Sign in with your apple ID, but then do NOT elect to use iCloud during this set-up run-through.  Once set-up is over, go into Settings>iCloud and turn on all the apps you want EXCEPT for safari.  This basically disables iCloud bookmark syncing, and should enable you to use Safari without crashing.

I have a follow-up call scheduled with an Apple Support Senior Advisor to figure out how to fix the bookmark "file" in my iCloud account so that I can re-enable bookmark syncing.

Good luck!

It was reassuring to find out that I wasn't the only one experiencing this problem, so I was happy to reply!

Yes, I agree the workaround was not ideal, but at least it got my device working again.  My first conversation with the Senior Advisor sounds similar to yours -- she told me how many bookmarks I had stored in iCloud, along with how many were duplicates (likely caused by the Chrome syncing snafu).  I'm hoping that my follow-up conversation will result in more than a bug report being sent to Engineering.  I'll post what I hear.

Thank you for pointing out the ability to use the Safari preference panel to change the folder used as the source of bookmarks which appear on the Safari landing page.  I like your hypothesis that the Chrome sync screwed up this connection.  I'll share this idea with the Senior Advisor and see if that gets us anywhere.

Cheers.

Exactly same Problem

I have same problem guys.

Since yesterday afternoon, Every time i opened safari on my iPhone and pressed either iCloud tab button on the bottom right or try type on the address bar, Safari crashed. After a long read on internet I went to the iCloud settings and turned off the switch for safari. Once i opened safari it worked fine.

I called Apple support and discussed this issue and we tried many things like reset the phone and set it up as a new device, signing on an other iPhone with my iCloud details to see if it was the device, but in the end we found that the problem was with iCloud account and not the device related because safari started crashing on that device too. It seems like that safari data on my iCloud got corrupted. I read some forums last years where a few users experience a similar issue.

Now can somebody suggest me any workaround to fix this. Since i cannot open safari on my iPhone, i went on my macbook and pressed the iCloud tab button to see which iCloud tabs were opened on my iPhone. it showed two tabs one with blank line but when i press on the line, it takes me to macupdate website.

Could these two tabs be the the culprit that they are still showing on my iPhone? Can I ask apple to reset my iCloud profile? If i wait 7 days for these two tabs to clear (if they clear), will my safari start working again on iPhone? Safari is working fine on macbook though.

Have you managed to sort out your problem if so, how?

Thanks

I Was so relived to find out that this didn't happen to only me. The exact same thing happend to me.  fix I found, was simply resetting the phone by holding down the home and power buttons for 7 seconds
